The B&K Precision 2532B is a two-channel digital storage oscilloscope offering 40 MHz of bandwidth, 500 MSa/s real-time sample rate on a single channel, and up to 32,000 points per channel of waveform memory. It is part of a two-model series — the 2530B at 25 MHz and the 2532B at 40 MHz — that combines core oscilloscope performance with advanced triggering, automated measurements, and analysis tools in a compact benchtop package. The instrument features a 5.7-inch color TFT display, an EasyScope PC software interface, and a multi-language user interface covering English, Simplified Chinese, Traditional Chinese, Arabic, French, German, Russian, Spanish, Portuguese, Japanese, Korean, and Italian.

B&K Precision positions the 2530B and 2532B for applications in education, troubleshooting and debug, and service and repair. For educational environments, the Auto Set button can be disabled — letting instructors require students to configure vertical, horizontal, and trigger parameters manually, much as they would on a traditional analog oscilloscope. A context-sensitive help system displays an on-screen description for any button pressed while help mode is active, supporting students and new users learning the instrument.

ValueTronics International is an authorized B&K Precision distribution partner and stocks the 2530B and 2532B series alongside the broader B&K Precision instrument catalog. All equipment is stored and tested in our 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Pre-owned units pass through our in-house inspection and performance verification process before shipment, and customers can request NIST-traceable calibration, ISO 17025 calibration with data, or Z540.3 guardbanding with data as part of the order — letting the same instrument enter a regulated quality system from day one with the documentation that system requires.

## Brand Heritage

B&K Precision Corporation is a long-established American test and measurement manufacturer headquartered in Yorba Linda, California, with origins tracing to the 1950s. The brand has remained continuously active under the B&K Precision name and is well known for value-tier benchtop instruments across oscilloscopes, power supplies, function generators, and DMMs.

## Compare Other Models in This Series

The 2530B and 2532B form a two-model digital storage oscilloscope series that shares a common platform — the same 5.7-inch color TFT display, the same 500 MSa/s single-channel sample rate, the same two-channel front end with 1 MΩ input impedance, the same 32-parameter automatic measurement set, and the same EasyScope PC software environment — and differs primarily in analog bandwidth and the resulting fastest timebase.

Because both models share the same acquisition system, math and FFT capability, trigger types, digital filter, waveform recorder, pass/fail testing, multi-language interface, and USB host and device connectivity, the choice between them is driven by the highest-frequency signal the user expects to characterize and by the rise times of the edges being measured. Both models cover the same set of educational, debug, service, and repair applications described in the datasheet.

Each pre-owned model below is listed on its own product page with condition-matched pricing, condition description, and availability. Use the comparison table that follows to align the bandwidth and rise-time specifications with the signals you actually need to measure, then click through to the individual page for full quote details.

Within this series, the 2532B is the higher-bandwidth model at 40 MHz with a specified rise time of <8.8 ns and a fastest timebase of 10 ns/DIV. The 2530B is the lower-bandwidth model at 25 MHz with a specified rise time of <14 ns and a fastest timebase of 25 ns/DIV. All other published specifications — sample rate, channel count, memory depth, vertical sensitivity, accuracy, trigger system, math and FFT, digital filtering, pass/fail testing, waveform recorder, display, interfaces, and environmental ratings — are identical between the two models.

The substantive differences between the two models live in three closely related specifications: analog bandwidth (25 MHz vs. 40 MHz), rise time (<14 ns vs. <8.8 ns), and minimum horizontal scan setting (25 ns/DIV vs. 10 ns/DIV). The 2532B's combination of higher bandwidth and faster minimum timebase makes it the better fit for slightly faster digital edges and higher-frequency analog signals; the 2530B is the right choice when the highest-frequency content of interest falls comfortably below the 25 MHz mark and lower-cost coverage is preferred.

The 2530B is published with a one-year warranty and the 2532B with a three-year warranty according to the datasheet — a difference that is worth weighing alongside the bandwidth selection. Refer to the comparison table for the side-by-side specification view and to the individual product pages for current pricing and condition options.
